Description of Hardware
10Base-T/
100Base-TX Ports
These ports are dual-speed RJ-45 ports with built-in wiring crossovers
(MDI-X). Workstations and servers can be connected to these ports with
straight-through cable. When connecting to another switch or a hub,
you can connect to a port on the attached device that does not have
built-in wiring crossovers (MDI) or use crossover cabling (see Appendix A
for a pin-out description of crossover cable).
Each of these ports support auto-negotiation, so the optimum
transmission mode (half- or full-duplex) and data rate (10 or 100 Mbps)
are selected automatically. If a device connected to one of these ports
does not support auto-negotiation, the communication mode of that
port can be configured manually.
